Put a few hours into DQ IV: Chapters of the Chosen the other day. It was the Euro release and was playing with an R4. Had an issue when chapter 2 starts and I try to take the female character out of the room it begins in.....well screens go black but music continues and is essentially locked up. Plugged that memcard(with the same save file) into an updated CycloDS running 1.51 and the issue repeats.

Yes I know there's another English release and I also could just delete the save file and start over again to see if it happens with the CDS, but guess I'm just trying to avert losing a few hours of playtime.
